Aiming to account for the dynamic nature of law, the Argentinian philosophers
Carlos Alchourrón and Eugenio Bulygin discriminate the concepts of legal
system and legal order. The first makes reference to a set of statements that
includes all their deductive consequences, among which there are norms that
prescribe coercive acts. It is a static entity. Legal order, on the other hand, is
conceived as a sequence of legal systems connected by some criterion of legal
validity and keeps its identity through the changes produced by the passing or
abrogation of laws.
The aim of this paper is to present arguments leading to support that the notion
of legal order is inadequate for its declared purpose and, furthermore, its
conception, with the meaning the authors assign to it, is unnecessary.
